ABSTRACT:
An improved process for the glycol dehydration of water-containing natural gas comprises contacting the natural gas and glycol in a contacting zone to produce a dried natural gas and a water-rich glycol, and heating the water-rich glycol in a regeneration zone to produce a water-lean glycol for reintroduction into the contacting zone and a water-containing gaseous overhead. The gaseous overhead is partially condensed and the resulting gaseous components are returned to the contacting zone. In a preferred embodiment, the glycol is further purified by contact in a separate stripping column with dry stripping gas under a pressure lower than that of the regeneration zone.
